Spinning and tumbling of long fibers in isotropic turbulence
Theresa B. Oehmke, Ankur D. Bordoloi, Evan Variano +1
We simultaneously measure both spinning and tumbling components of rotation for long near-neutrally buoyant fibers in homogeneous and isotropic turbulence. The lengths and diameter…

Lagrangian time scale of rotation for inertial fibers in isotropic turbulence
Ankur D. Bordoloi, Gautier Verhille, Evan Variano
Using time-resolved measurements of the orientation of rigid inertial fibers in a turbulence-tank, we investigate the autocorrelation of their tumbling rate. The correlation time (…

Turbulence statistics in a negatively buoyant multiphase plume
Ankur D. Bordoloi, Chris C. K. Lai, Laura K. Clark +2
We investigate the turbulence statistics in a {multiphase plume made of heavy particles (particle Reynolds number at terminal velocity is 450)}. Using refractive-index-matched ster…
